如何在C#中从数据库中选择下一行？

Question

这是代码，我试过了，但它不起作用。

con.Open();
String sql = "SELECT * from bills order by sr_no OFFSET 10 ROWS ONLY ";
cmd = new OleDbCommand(sql, con);
dr1 = cmd.ExecuteReader(CommandBehavior.CloseConnection);
dataGridView1.Rows.Clear();
while (dr1.Read() == true)
{
    dataGridView1.Rows.Add(dr1[0], dr1[3]);
}
con.Close();

Answer 1

使用 OFFSET 和 FETCH ：

SELECT col1, col2, ...
FROM ...
WHERE ... 
ORDER BY -- this is a MUST there must be ORDER BY statement
-- the paging comes here
OFFSET     10 ROWS       -- skip 10 rows
FETCH NEXT 10 ROWS ONLY; -- take 10 rows

Answer 2

SELECT * from bills order by sr_no OFFSET number_of_rows_u_want_to_skip ROWS FETCH NEXT number_of_rows_u_want_to_take  ROWS ONLY
